Every law school will require law students to complete with a grade "C" or higher the following courses: Contract Law, Property Law, Civil Procedure, Criminal Procedure, Criminal Law, and Constitutional Law. Also, there is a Legal Research and Writing class.
Now, there are a lot of electives you can take in law school. For example, if you want to be a corporate lawyer, you should take Business Associations, Corporate Tax, Securities Law, and Antitrust Law. My advice to you is to read law journals to determine what type of law you want to practice and then find the law school that will give you the best training in that field.
Good luck, I hope this was helpful
